Copper-based oil bearing has the characteristics of low cost, vibration absorption, low noise, and no need to add lubricating oil for a long working time. It is especially suitable for working environments that are not easy to lubricate or do not allow oil to be dirty.

Copper-based oil bearing (Porous Bearing) is a sintered body made of powder metallurgy with metal powder as the main raw material. It is inherently porous and has the ability to freely adjust the number of pores during the manufacturing process. , size, shape and distribution of technical advantages. Using the porosity of the sintered body, it is impregnated with 10%~40% (volume fraction) lubricating oil and used in the state of self-oil supply. The copper-based oil bearing manufacturer tells you that when the bearing temperature rises during operation, because the expansion coefficient of oil is larger than that of metal, it automatically enters the sliding surface to lubricate the bearing, and when it stops working, the oil is sucked back into the pores with the temperature drop.
Porosity is an important parameter for oil-impregnated bearings. Oil-impregnated bearings that work at high speed and light load require a large amount of oil and high porosity; oil-impregnated bearings that work at low speeds and large loads require high strength and low porosity. The copper-based oil bearing manufacturer tells you that this kind of bearing was invented in the early 20th century. Because of its low manufacturing cost and convenient use, it has been widely used. Now it has become a part of automobiles, home appliances, audio equipment, office equipment, agricultural machinery, precision machinery, etc. A class of basic parts that are indispensable for the development of various industrial products.
